Infrared Absorption Spectra of Some Aldofuranoid, Aldopyranoid, and Acyclic l-Acylamido Derivatives of Sugars.

The infrared absorption spectra of two glycofuranosylacetamides and their perbenzoates, and of eleven glycopyranosylacylamides and eight esters thereof, are presented and discussed. For comparison, the spectra of thirteen 1,1-bis(acylamido)-1-deoxyalditols and eight esters thereof are also given and discussed. The useful correlations between structure and infrared absorption made by Barker and co-workers for certain carbohydrates, and by Nanasi and co-workers for some -arylglycosylamines, cannot be extended to the 1-acylamido compounds we have studied.
